Description

A method, device and storage medium for determining transmission configuration indication status

Technical Field

The present disclosure relates to the field of communication technology, and in particular to a method, device and storage medium for determining a transmission configuration indication state.

Background Art

In the new wireless technology (New Radio, NR), for example, when the communication frequency band is in frequency range 2, since the high-frequency channel attenuates quickly, in order to ensure the coverage range, beam-based transmission and reception are required.

In related technologies, beams can be indicated by transmission configuration indication (TCI) state or spatial relation information (spatialrelationinfo). In the method of TCI state indicating beams, the TCI state corresponding to each physical channel can be indicated based on signaling. In order to reduce signaling overhead, 3GPP introduced a unified transmission configuration indication state (unified TCI state).

To reduce signaling overhead, 3GPP introduced a unified transmission configuration indication state (unified TCI state). The unified TCI state currently includes the downlink transmission configuration indication state (DL TCI state) and the uplink transmission configuration indication state (UL TCI state) for uplink and downlink respectively, or the joint uplink and downlink indication (joint TCI state). If the network device indicates a DL TCI state for downlink, the TCI state can be used for the physical downlink channel (PDCCH, PDSCH) of the terminal, and a part of the CSI-RS (such as the sounding reference signal (SRS)). If the network device indicates a TCI state for uplink, the TCI state can be used for the physical uplink channel (PUCCH, PUSCH) of the terminal, and a part of the SRS. If the network device indicates a joint TCI state, the TCI state can be used for both uplink and downlink channels/reference signals.

At present, only when the unified TCI state is configured for the single-transmission reception point (S-TRP), the SRS resource can determine the unified TCI state corresponding to the SRS resource by configuring whether to use the unified TCI state corresponding to the S-TRP. When the unified TCI state is configured for the M-TRP, how to determine the TCI stat corresponding to the SRS resource is a problem that needs to be solved.

Referring to Figure 1, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device through wireless resources and performs data transmission.

The embodiments of the present disclosure do not limit the number of network devices and terminals included in the wireless communication system.

It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. Wireless communication systems can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access/collision avoidance. According to the capacity, rate, latency and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, which can also be called new radio network (New Radio, NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as a network.

Further, the network equipment involved in the present disclosure may also be referred to as a wireless access network equipment. The wireless access network equipment may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in an NR system, or it may also be a component or a part of a base station. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network equipment are not limited. In the present disclosure, the network equipment may provide communication coverage for a specific geographical area, and may communicate with a terminal located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network equipment may also be a vehicle-mounted device.

Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., which is a device that provides voice and/or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a customer premises equipment (Customer Premise Equipment, CPE), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

In NR, especially when the communication frequency band is in frequency range 2, since the high-frequency channel attenuates quickly, beam-based transmission and reception are required to ensure coverage.

In some embodiments of the present disclosure, beams of PDCCH, physical downlink shared channel (PDSCH), physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) and/or reference signals are independently indicated, and PDCCH and PUCCH use Media Access Control-Control Unit (MACC). Element, MAC CE) to activate a beam, while PDSCH and PUSCH are DCI signaling to indicate their respective beams. Among them, the reference signal includes the Channel Status Information-Reference Signal (CSI-RS), the Sounding Reference Signal (SRS), the Positioning Reference Signal (PRS), the Timing Reference Signal (TRS), etc. CSI-RS includes CSI-RS for channel state information measurement or CSI-RS for beam measurement or CSI-RS for path loss estimation. SRS includes SRS for channel state information measurement based on codebook or non-codebook or SRS for beam measurement or SRS for antenna switching or SRS for positioning measurement.

In some embodiments of the present disclosure, in order to reduce signaling overhead, it is desired to use a unified TCI state. The unified TCI state may currently be separately indicated for uplink and downlink, including DL TCI state and UL TCI state, or a joint TCI state for uplink and downlink. That is, if the base station indicates a DL TCI state for downlink, then the TCI state can be used for the PDSCH and PDCCH (such as UE-specific PDCCH) of the terminal, and a part of the CSI-RS (such as aperiodic CSI-RS); if the base station indicates a TCI state for uplink, then the TCI state can be used for the PUSCH and PUCCH of the terminal, and a part of the SRS. If the base station indicates a jointTCIstate, then the TCI state can be used for both uplink and downlink channels/reference signals.

In some embodiments of the present disclosure, only the unified TCI state of S-TRP is considered, that is, only one set of TCI state indication methods (including joint TCI state, or DL TCI state and UL TCI state) is considered. It is not yet certain how to indicate in the case of M-TRP. In the case of M-TRP, the S-DCI method is included. Corresponding to PDCCH, PDSCH, PUCCH and PUSCH, if the PXXCH is configured with M-TRP and the other part PYYCH is configured with S-TRP, then when the TCI state indication information indicates two sets of TCI states, even for the PXXCH configured with M-TRP, it may be necessary to implement dynamic switching of M-TRP and S-TRP. Then how to determine which one or both of the two sets of TCI states each channel corresponds to requires additional signaling indication.

Currently, PDCCH is based on Radio Resource Control (RRC) signaling to determine which one or both of the two TCI states each CORESET or CORESET group uses to receive PDCCH;

PUCCH is also based on RRC signaling to determine which one or both of the two sets of TCI states each PUCCH or PUCCH group uses to send PUCCH.

PDSCH determines which one or both of the two TCI states are used for PDSCH reception based on the first indication field of PDSCH in DCI.

PUSCH is based on the second indication field of PUSCH in DCI to determine which one or both of the two sets of TCI states each PUSCH is based on to send PUSCH.

In some embodiments of the present disclosure, when only the unified TCI state of S-TRP is considered, the sounding reference signal (SRS) can be determined based on whether the follow unifiedTCI state is configured. The unified TCI state is still not used. However, when M-TRP transmission is used, how to determine the unified TCI state corresponding to the SRS resource is a problem that needs to be solved.

In view of this, an embodiment of the present disclosure provides a method for determining a transmission configuration indication state, by determining N sets of unified TCI states, and based on the N sets of unified TCI states, determining the unified TCI state corresponding to the SRS resources, providing a method for determining the unified TCI state corresponding to the SRS resources, thereby improving the transmission flexibility of the SRS resources based on the unified TCI state.

Fig. 2 is a flow chart showing a method for determining a transmission configuration indication state according to an exemplary embodiment. As shown in Fig. 2 , the method is executed by a terminal and includes the following steps.

In step S11, N sets of unified TCI states are determined.

Wherein, N is a positive integer greater than 1.

In step S12, based on N sets of unified TCI states, the unified TCI state corresponding to the SRS resources is determined.

In the embodiments of the present disclosure, the transmission configuration indication state determination method can be used to determine the unified TCI state corresponding to the SRS resource when the M-TRP is transmitted based on the S-DCI scheduling. It should be noted that the SRS resources in all the embodiments of the present disclosure include at least one of aperiodic SRS resources, periodic SRS resources and semi-persistent SRS resources.

In the disclosed embodiment, the terminal may determine N sets of unified TCI states, where N is a positive integer greater than 1. Each set of unified TCI states may include a joint TCI state, or each set of unified TCI states may include at least one of a DL TCI state and a UL TCI state.

Furthermore, the terminal may determine the unified TCI state corresponding to the SRS resource based on the determined N sets of unified TCI states, wherein the SRS resource may be a resource determined at a granularity of an SRS resource set.

By adopting the technical solution of the embodiment of the present disclosure, N sets of unified TCI states are determined, and based on the N sets of unified TCI states, the unified TCI states corresponding to SRS resources are determined. A method for determining the unified TCI states corresponding to SRS resources is provided, thereby improving the transmission flexibility of SRS resources based on the unified TCI states.

FIG3 is a flowchart of a method for determining N sets of unified TCI states according to an exemplary embodiment. As shown in FIG3 , the method includes the following steps.

In step S21, first indication information is received.

Among them, the first indication information is used to indicate M sets of unified TCI state, where M is a positive integer.

In step S22, based on the first indication information, N sets of unified TCI states are determined.

In the disclosed embodiment, the terminal may receive the first indication information and determine N sets of unified TCI states based on the first indication information. The first indication information is used to indicate M sets of unified TCI states, where M is a positive integer.

In the embodiment of the present disclosure, the first indication information received by the terminal may include information received L times, and the information received for the i-th time The information is used to indicate M _i sets of unified TCI states, where L is a positive integer and i is a positive integer less than or equal to L.

In one example, the first indication information received by the terminal may include information received L times, wherein the information received for the i-th time indicates _Mi sets of unified TCI states. For different values of i, the value of _Mi may be different or the same. For example, if Mi is ₁ , that is, the information received for the first time corresponds to one set of unified TCI states, then _M2 may be 1, 2 or other values, that is, the information received for the second time may correspond to one set of unified TCI states, or two sets of unified TCI states, or more sets of unified TCI states. And so on.

In the above example, optionally, the information received L times may come from H transmission points respectively, where H is a positive integer less than or equal to L.

At this time, the N sets of unified TCI states can be determined in the following manner: based on _Mi sets of unified TCI states; or based on _Mi sets of unified TCI states and _Mj sets of unified TCI states, where j is a positive integer less than or equal to L, and i is not equal to j.

In the embodiment of the present disclosure, when N sets of unified TCI states are determined based on _Mi sets of unified TCI states, i may be equal to L, that is, _Mi sets of unified TCI states are determined based on the information received for the Lth time, and the information received for the Lth time is the most recently received information, and then N sets of unified TCI states are determined based on _Mi sets of unified TCI states. Still taking the above-mentioned terminal receiving L information as an example, N sets of unified TCI states may be determined based on M _L sets of unified TCI states indicated by the information received for the Lth time, and at this time i=L. Among them, _Mi may be the maximum value among M ₁ , M ₂ , ..., M _L , or may not be the maximum value among M ₁ , M ₂ , ..., M _L. Further, when M _L =1, the M _L-1 sets of unified TCI states indicated by the information received for the L-1th time are determined as N sets of unified TCI states, until the value of M _Lp obtained is greater than 1, and p is 0 or a positive integer less than L.

In the embodiment of the present disclosure, when N sets of unified TCI states are determined based on M _i sets of unified TCI states and M _j sets of unified TCI states, i may be equal to L, that is, M _i sets of unified TCI states are determined based on information received for the Lth time, and the information received for the Lth time is the information received most recently. Further, j may be less than i, and M _j sets of unified TCI states are determined based on information received for the jth time, and the information received for the jth time is information received before the information received for the ith time, and the information received for the Lth time does not update at least one set of unified TCI states in the M _j sets of unified TCI states.

Still taking the above-mentioned terminal receiving information L times as an example, if the information received by the terminal for the jth time indicates M _j sets of unified TCI states, and the information received by the terminal for the Lth time indicates _Mi sets of unified TCI states, wherein the _Mi sets of unified TCI states do not include an update of at least one set of unified TCI states in the M _j sets of unified TCI states, then the N sets of unified TCI states can be determined based on the M _j sets of unified TCI states and the _Mi sets of unified TCI states. For example, the information received by the terminal for the M _jth time previously indicated 2 sets of unified TCI states, including the first set and the second set, and the information received by the terminal for the most recent time, i.e., the M _Lth time, indicated 1 set of unified TCI states, and the 1 set of unified TCI states updated the first set of unified TCI states indicated in the information received for the M _jth time, and updated the first set of unified TCI states indicated in the information received for the M _jth time. If the second set of unified TCI states indicated in the information is not updated, N sets of unified TCI states can be determined based on the updated first set of unified TCI states in the information received for the M _Lth time and the second set of unified TCI states in the information received for the M _jth time, where N=2.

Fig. 4 is a schematic diagram of a method for determining N sets of unified TCI states from information received at least once according to an exemplary embodiment. As shown in Fig. 4, the terminal receives L pieces of information as the first indication information, wherein the information received for the Lth time is the most recently received information in the first indication information, and the information received for the Lth time indicates two sets of unified TCI states, namely unified TCI state1 and unified TCI state2. At this time, it can be directly determined that the two sets of unified TCI states indicated by the information received for the Lth time, namely unified TCI state1 and unified TCI state2, are N sets of unified TCI states.

Fig. 5 is a schematic diagram of a method for determining N sets of unified TCI states from information received at least once according to an exemplary embodiment. As shown in Fig. 5, the terminal receives L pieces of information as the first indication information, wherein the information received for the Lth time is the information received most recently in the first indication information, the information received for the i-th time is the information received before the Lth time, the information received for the i-th time indicates 2 sets of unified TCI states, namely unified TCI state1 and unified TCI state2, and the information received for the Lth time indicates 1 set of unified TCI states, namely unified TCI state1', wherein unified TCI state1' is an update of unified TCI state1 indicated by the information received for the i-th time. At this time, unified TCI state1' and unified TCI state2 can be determined as N sets of unified TCI states.

By adopting the technical solution of the embodiment of the present disclosure, N sets of unified TCI states are determined by first indication information including at least one received information, a configuration method of unified TCI state is provided during M-TRP transmission based on S-DCI scheduling, and the transmission flexibility based on unified TCI state is improved.

In the embodiment of the present disclosure, determining N sets of unified TCI states based on the first indication information can be achieved in the following manner: receiving second indication information, the second indication information is used to activate multiple code points corresponding to the TCI state field of the first indication information, and each code point in the multiple code points corresponds to M sets of unified TCI states. Further, in response to receiving the second indication information but not receiving the first indication information, determining N sets of unified TCI states based on the M sets of unified TCI states corresponding to the default code points in the multiple code points.

Among them, the first indication information can be carried in the DCI, and the second indication information can be carried in the MAC CE. Multiple code points corresponding to the TCI state field of the DCI can be activated based on the MAC CE, each of the multiple code points corresponds to M sets of unified TCI states, and N sets of unified TCI states are determined based on the M sets of unified TCI states. Further, when the MAC CE is received but the DCI has not been received, the N sets of unified TCI states can be determined based on the M sets of unified TCI states corresponding to the default code points among the multiple code points corresponding to the TCI state field of the DCI activated by the MAC CE. In one example, when the MAC CE is received but the DCI has not been received, since the MAC CE can be used to activate the M sets of unified TCI states corresponding to the multiple code points corresponding to the TCI state field of the DCI (that is, each of the multiple code points corresponds to M sets of unified TCI states, and the M values corresponding to each code point may be the same or different), in this case, the N sets of unified TCI states may be determined based on a default code point, for example, the M sets of unified TCI states corresponding to the code point with the smallest code point identifier among the code points.

In the disclosed embodiment, the SRS resources include at least one of the following: SRS resources for codebook transmission; SRS resources for non-codebook transmission; SRS resources for antenna switching; SRS resources for beam management. Among them, the SRS resources for codebook transmission and the SRS resources for non-codebook transmission are SRS resources for channel status information (CSI) measurement.

In the M-TRP transmission scenario based on S-DCI scheduling, the terminal may receive multiple first indication information, some of which may indicate only one set of unified TCI states, while other first indication information may indicate multiple sets of unified TCI states. The specific number of receiving one set of unified TCI states and multiple sets of unified TCI states may be allocated according to actual needs, but at least one first indication information received is used to indicate multiple sets of unified TCI states. At this time, how to determine the unified TCI state corresponding to the SRS resource based on the multiple sets of unified TCI states requires further agreement.

In the disclosed embodiment, based on N sets of unified TCI state, determining the unified TCI state corresponding to the SRS resource can be: determining the unified TCI state corresponding to the SRS resource based on third indication information, the third indication information is used to configure whether the SRS resource adopts the unified TCI state, that is, whether to follow unified TCI state; and/or used to configure the SRS resource to adopt one or more sets of unified TCI state among the N sets of unified TCI state.

In one example, the third indication information may include a first indication field and a second indication field, wherein the first indication field may be used to configure whether the SRS resource follows unifiedTCIstate. The second indication field may be used to configure the SRS resource to adopt one or more of N sets of unified TCI states.

In the disclosed embodiment, the first indication field configures the SRS resource to follow unifiedTCIstate, and the unifiedTCIstate adopted by the SRS resource may be N sets of unified TCI states. Further, the SRS resource is configured to adopt one or more sets of unified TCI states among the N sets of unified TCI states through the second indication field.

Among them, the third indication information can be carried in RRC signaling or MAC CE. The SRS resources can be configured to use at least one of the N unified TCI states, or not use at least one of the N unified TCI states, through RRC signaling or MAC CE. Further, when the SRS resources are configured to use at least one of the N unified TCI states, it is also possible to configure which one or more of the N unified TCI states the SRS resources use through RRC signaling or MAC CE, that is, which one or more of the N unified TCI states are used to transmit the SRS resources.

In the embodiment of the present disclosure, when configuring the SRS resource to use at least one of the N unified TCI states, the unified TCI state corresponding to the SRS resource can be determined by at least one of the following methods: One or N sets of unified TCI states among the N sets of unified TCI states indicated by the indication information are determined as the unified TCI states corresponding to the SRS resources; based on the default rule, one or N sets of unified TCI states among the N sets of unified TCI states are determined as the unified TCI states of the SRS resource set.

In the disclosed embodiment, one or N sets of unified TCI states among N sets of unified TCI states may be further determined as unified TCI states corresponding to SRS resources through fourth indication information. The fourth indication information may be carried in MAC CE and/or DCI. Furthermore, the fourth indication information may be the same as the third indication information.

In the disclosed embodiment, one or N sets of unified TCI states among N sets of unified TCI states can also be determined as the unified TCI state corresponding to the SRS resources based on the default rules.

In the disclosed embodiment, the SRS resource may include one or more SRS resource sets. When the SRS resource includes N SRS resource sets, that is, the number of resource sets is the same as the number of determined unified TCI state sets, the unified TCI state corresponding to each SRS resource set in the SRS resource may be determined in the following manner: in response to the number of SRS resource sets being N, based on the default association relationship, the unified TCI state having a default association relationship with the SRS resource set is determined in the N sets of unified TCI states as the unified TCI state corresponding to the SRS resources included in the SRS resource set.

For example, the terminal determines two sets of unified TCI states, namely unified TCI state1 and unified TCI state2. At the same time, the SRS resources include two SRS resource sets, namely SRS resource sets set1 and set2, and set1 has a default association relationship with unified TCI state1, and set2 has a default association relationship with unified TCI state2. On this basis, set1 in the SRS resources can be configured to be associated with unified TCI state1 in N sets of unified TCI states, and set2 can be associated with unified TCI state2. Those skilled in the art can understand that the default association relationship can be set according to actual needs. For example, it can also be set that set1 has a default association relationship with unified TCI state2, and set2 has a default association relationship with unified TCI state1. In this case, set1 can be configured to be associated with unified TCI state2, and set2 can be configured to be associated with unified TCI state1. And so on.

On the other hand, when the SRS resources include K SRS resource sets, K is a positive integer less than N, that is, the number of resource sets is less than the determined number of unified TCI states, the unified TCI state corresponding to each SRS resource set in the SRS resources can be determined in the following way: in response to the number of SRS resource sets being K, the default K sets of unified TCI states among the N sets of unified TCI states are determined as the unified TCI states of the K SRS resource sets.

For example, the terminal determines two sets of unified TCI states, namely unified TCI state1 and unified TCI state2. At the same time, the SRS resources include an SRS resource set set1, and set1 has a default association relationship with unified TCI state1. On this basis, you can configure set1 to be associated with unified TCI state1. Similarly, you can also set set1 to have a default association relationship with unified TCI state2, and then you can configure set1 to be associated with unified TCI state2. And so on.

In the embodiment of the present disclosure, when the number of resource sets is less than the number of sets of the determined unified TCI state, The unified TCI state corresponding to each SRS resource set in the SRS resource is determined in the following manner: in response to the number of SRS resource sets being K, K sets of unified TCI states in the unified TCI state corresponding to CORESET are determined as the unified TCI states of the K SRS resource sets.

For example, the SRS resource includes an SRS resource set set1, which can determine the CORESET with the smallest identifier in the CORESET corresponding to the terminal, and determine the unified TCI state corresponding to the set1 based on the unified TCI state corresponding to the CORESET with the smallest identifier. When the CORESET with the smallest identifier corresponds to only one set of unified TCI states, the set of unified TCI states can be directly determined to be the unified TCI state corresponding to set1. When the CORESET with the smallest identifier corresponds to multiple sets of unified TCI states, the first set of unified TCI states among the multiple sets of unified TCI states can be determined to be the unified TCI state corresponding to set1. The CORESET with the smallest identifier may be the CORESET with the smallest identifier among the CORESETs contained in the time slot of the search space (search space) most recently monitored; the CORESET with the smallest identifier may also be the CORESET with the smallest identifier on the active part bandwidth (active BandWidth Part, active BWP); the CORESET with the smallest identifier may also be the CORESET with the smallest identifier corresponding to the terminal.

In the disclosed embodiment, when the number of resource sets is less than the number of determined unified TCI states, the unified TCI state corresponding to each SRS resource set in the SRS resources can also be determined in the following manner: in response to the number of SRS resource sets being K, the K sets of unified TCI states in the unified TCI state corresponding to the physical downlink shared channel PDSCH are determined as the unified TCI state of the K SRS resource sets.

For example, the SRS resource includes one SRS resource set set1, which can determine the unified TCI state corresponding to the PDSCH of the terminal, and determine the unified TCI state corresponding to the set1 based on the unified TCI state corresponding to the PDSCH. When the PDSCH corresponds to only one set of unified TCI states, the set of unified TCI states can be directly determined as the unified TCI state corresponding to set1. When the PDSCH corresponds to multiple sets of unified TCI states, the first set of unified TCI states in the multiple sets of unified TCI states can be determined as the unified TCI state corresponding to set1. The unified TCI state corresponding to the PDSCH can be one or more of the N sets of unified TCI states determined based on the indication field in the DCI signaling, or can also be one or more of the N sets of unified TCI states determined based on the default rule. The indication field in the DCI signaling is used to indicate which one or more of the N sets of unified TCI states are used for the transmission of the PDSCH.

In the disclosed embodiment, the first indication information may be carried in the media access control unit MAC CE, or the first indication information may be carried in the downlink control information DCI and the media access control unit MAC CE.

When the first indication information is carried in the downlink control information DCI and the media access control unit MAC CE, the multiple code points of the TCI state field used by MAC CE to activate the DCI correspond one-to-one to the K sets of unified TCI states, and the TCI state field of DCI is used to indicate one code point among the multiple code points. Among the multiple code points in the TCI state field of the DCI activated by MAC CE, at least one code point corresponds to multiple sets of unified TCI states. That is, in the K sets of unified TCI states corresponding to at least one code point, K is a positive integer greater than 1.

When the first indication information is carried in the media access control unit MAC CE, MAC CE is used to activate K sets of unified TCI states, which correspond to the first code point of the TCI state field of DCI. In other words, at this time, MAC CE only activates one code point of the TCI state field of DCI, namely the first code point, so N sets of unified TCI states can be determined based on the K sets of unified TCI states corresponding to the first code point.

Fig. 6 is a flow chart showing a method for determining a transmission configuration indication state according to an exemplary embodiment. As shown in Fig. 6 , the method is executed by a network device and includes the following steps.

In step S31, configure N sets of unified TCI states.

Among them, N sets of unified TCI states are used to determine the unified TCI state corresponding to the SRS resources, and N is a positive integer greater than 1.

In an embodiment of the present disclosure, the transmission configuration indication state determination method can be used to determine the unified TCI state corresponding to the SRS resource when M-TRP is transmitted based on S-DCI scheduling.

In the disclosed embodiment, the network device may be configured with N sets of unified TCI states, where N is a positive integer greater than 1. Each set of unified TCI states may include a joint TCI state, or each set of unified TCI states may include at least one of a DL TCI state and a UL TCI state.

Furthermore, the N sets of unified TCI states configured by the network device can be used to determine the unified TCI states corresponding to the SRS resources. The SRS resources can be resources determined at the granularity of the SRS resource set.

Figure 7 is a flowchart of a method for determining N sets of unified TCI states according to an exemplary embodiment. As shown in Figure 7, the method includes the following steps.

In step S41, first indication information is sent.

In the disclosed embodiment, the network device may send a first indication message, where the first indication message is used to indicate M sets of unified TCI states, thereby enabling the terminal to determine the unified TCI state corresponding to the SRS resource based on the M sets of unified TCI states.

The first indication information sent by the network device may include information sent L times, wherein the information sent for the i-th time indicates _Mi sets of unified TCI states. For different values of i, the value of _Mi may be different or the same. For example, if Mi is ₁ , that is, the information sent for the first time corresponds to one set of unified TCI states, then _Mi may be 1, 2 or other values, that is, the information sent for the second time may correspond to one set of unified TCI states, or two sets of unified TCI states, or more sets of unified TCI states. And so on.

In the above example, optionally, the information sent L times may come from H transmission points respectively, where H is a positive integer less than or equal to L.

At this time, the N sets of unified TCI states included in the first TCI state can be determined in the following manner: based on _Mi sets of unified TCI states; or based on _Mi sets of unified TCI states and _Mj sets of unified TCI states, where j is a positive integer less than or equal to L, and i is not equal to j.

In the embodiment of the present disclosure, when N sets of unified TCI states are determined based on _Mi sets of unified TCI states, i can be equal to L, that is, _Mi sets of unified TCI states are determined based on the information sent for the Lth time, the information sent for the Lth time is the most recently sent information, and then N sets of unified TCI states are determined based on _Mi sets of unified TCI states.

In the embodiment of the present disclosure, when N sets of unified TCI states are determined based on M _i sets of unified TCI states and M _j sets of unified TCI states, i may be equal to L, that is, M _i sets of unified TCI states are determined based on information sent for the Lth time, and the information sent for the Lth time is the most recently sent information. Further, j may be less than i, and M _j sets of unified TCI states are determined based on information sent for the jth time, and the information sent for the jth time is information sent before the information sent for the ith time, and the information sent for the Lth time does not update at least one set of unified TCI states in the M _j sets of unified TCI states.

By adopting the technical solution of the embodiment of the present invention, N sets of unified TCI states are determined by first indication information including at least one sent information, a configuration method of unified TCI state is provided during M-TRP transmission based on S-DCI scheduling, and the transmission flexibility based on unified TCI state is improved.

In the disclosed embodiment, determining N sets of unified TCI states based on the first indication information can be achieved by sending a second indication information, where the second indication information is used to activate multiple code points corresponding to the TCI state field of the first indication information, each of the multiple code points corresponding to M sets of unified TCI states. Further, determining N sets of unified TCI states based on the M sets of unified TCI states corresponding to the default code points among the multiple code points.

The first indication information may be carried in the DCI, and the second indication information may be carried in the MAC CE. Multiple code points corresponding to the TCI state field of the DCI may be activated based on the MAC CE, each of the multiple code points corresponds to M sets of unified TCI states, and N sets of unified TCI states are determined based on the M sets of unified TCI states. Further, when the terminal receives the MAC CE sent by the network device but has not yet received the DCI, the M sets of unified TCI states corresponding to the default code points among the multiple code points corresponding to the TCI state field of the DCI activated based on the MAC CE may be determined.

In the embodiment of the present disclosure, the SRS resource includes at least one of the following: an SRS resource for codebook transmission; an SRS resource for non-codebook transmission; an SRS resource for antenna switching; and an SRS resource for beam management. Among them, the SRS resource for codebook transmission and the SRS resource for non-codebook transmission are SRS resources for CSI measurement.

In the M-TRP transmission scenario based on S-DCI scheduling, the network device may send multiple first indication information, wherein some of the first indication information sent may only indicate a set of unified TCI states, while other first indication information sent may indicate only one set of unified TCI states. The information can indicate multiple sets of unified TCI states. The specific number of times of sending one set of unified TCI states and multiple sets of unified TCI states can be allocated according to actual needs, but at least one of the first indication information sent is used to indicate multiple sets of unified TCI states. At this time, how to determine the unified TCI state corresponding to the SRS resource based on the multiple sets of unified TCI states requires further agreement.

In the disclosed embodiment, based on N sets of unified TCI states, determining the unified TCI state corresponding to the SRS resource can be: sending a third indication information, the unified third indication information corresponding to the resource is used to configure whether the SRS resource follows the unifiedTCIstate; and/or used to configure the SRS resource to adopt one or more sets of unified TCI states among the N sets of unified TCI states.

In the embodiment of the present disclosure, when SRS resources are configured to adopt at least one set of N sets of unified TCI states, the unified TCI state corresponding to the SRS resources can be determined by at least one of the following methods: determining one or N sets of unified TCI states among the N sets of unified TCI states indicated by the fourth indication information as the unified TCI state corresponding to the SRS resources; based on the default rule, determining one or N sets of unified TCI states among the N sets of unified TCI states as the unified TCI state of the SRS resource set.

In the disclosed embodiment, the network device may further send fourth indication information to determine that one or N sets of unified TCI states among N sets of unified TCI states are unified TCI states corresponding to SRS resources through the fourth indication information. The fourth indication information may be carried in MAC CE and/or DCI. Furthermore, the fourth indication information may be the same as the third indication information.

For example, the terminal determines two sets of unified TCI states, namely unified TCI state1 and unified TCI state2. At the same time, the SRS resources include two SRS resource sets, namely SRS resource sets set1 and set2, and set1 has a default association relationship with unified TCI state1, and set2 has a default association relationship with unified TCI state2. On this basis, set1 in the SRS resources can be configured to be associated with unified TCI state1 in N sets of unified TCI states, and set2 can be associated with unified TCI state2. Those skilled in the art can understand that the default association relationship can be set according to actual needs. For example, set1 can also be set to have a default association relationship with unified TCI state2, and set2 can be set to have a default association relationship with unified TCI state1. In this case, set1 can be configured to be associated with unified TCI state2, and set2 can be configured to be associated with unified TCI state1. And so on.

In the disclosed embodiment, when the number of resource sets is less than the determined number of unified TCI states, the unified TCI state corresponding to each SRS resource set in the SRS resources can also be determined in the following manner: in response to the number of SRS resource sets being K, the K sets of unified TCI states in the unified TCI state corresponding to CORESET are determined as the unified TCI states of the K SRS resource sets.

In the embodiment of the present disclosure, when the number of resource sets is less than the number of determined unified TCI states, the unified TCI state corresponding to each SRS resource set in the SRS resource may also be determined in the following manner: The total number is K, and the K sets of unified TCI states in the unified TCI state corresponding to the physical downlink shared channel PDSCH are determined as the unified TCI state of the K SRS resource sets.

When the first indication information is carried in the downlink control information DCI and the media access control unit MAC CE, the multiple code points used by MAC CE to activate the TCI state field of DCI correspond to K sets of unified TCI states one by one, and the TCI state field of DCI is used to indicate one code point among the multiple code points. Among the multiple code points in the TCI state field of DCI activated by MAC CE, at least one code point corresponds to multiple sets of unified TCI states. That is, among the K sets of unified TCI states corresponding to at least one code point, K is a positive integer greater than 1.
